OSNews, Generic OSes The micro vs. monolithic kernel debate is now very much alive. Not too long ago, I wrote an article on the merits of microkernels, while a week later we featured a retort. Now, the greatest proponent of the microkernel steps in-- yes, Andy Tanenbaum writes: "Microkernels - long discarded as unacceptable because of their lower performance compared with monolithic kernels - might be making a comeback in operating systems due to their potentially higher reliability, which many researchers now regard as more important than performance." Now, we only need Torvalds to chime in, and it's 1992 all over again.

Hardly. Hindsight may make it seem that way, but there was still much development ahead in 1992.

1992 saw the release of the Alpha processor, and preceded the release of the PowerPC alliance. MIPS had just done the MIPS IV 64-bit processor architecture, and PA-RISC and SPARC were yet to enter the 64-bit world.

The fastest x86 was the i486 DX2 66, which was humiliated by all the RISC CPUs of the time (including SPARC), was a joke. It was by no means clear that Windows would be as dominant as it turned out to be with OS/2 still on the scene and MS hanging on using illegal means, so the future of the OS was still potentially up for grabs.

Merced was but a glimmer in Intel and HPs eye. And Itanium is hardly an x86 processor anyway.

And where are Intergraph now? Basically just another Wintel OEM.

Only one company actually make x86 competitive. AMD. Without competition, x86 would suck more than they do now.
